为什么在将<？xml version =“1.0”encoding =“utf-8”？>添加到网页时无法进行托管？

I am developing a simple webpage at hostgator.com. I have the standard headers, but when I add the following line:

<?xml version="1.0" encoding="utf-8"?>

the page does not work. I would like why.

This is the full header:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1 /DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="es" xml:lang="es"> 
... rest of code ...

The server returns me a blank page

Issue solved: The PHP short tags was open.

    My best guess is that:

    … so the server is trying to process the XML declaration as PHP code. Normally I'd expect an error message, but perhaps there is a PHP setting in play that suppresses errors to the client to avoid leaking data that could be potentially useful to someone trying a security exploit.

    Just remove it.

    • UTF-8 is the default
    • version 1.0 is the default
    • It is optional in the spec
    • Given a text/html content-type, an XML prolog will trigger IE6's quirks mode

    The latter is undesirable. The former all mean it makes no difference.
